#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ABSTRACT_UNIX_SOCKET, char *path);
Enables the use of an abstract Unix domain socket instead of establishing a TCP connection to a host. The parameter should be a char * to a null-terminated string holding the path of the socket. The path is set to path prefixed by a NULL byte. This is the convention for abstract sockets, however it should be stressed that the path passed to this function should not contain a leading NULL byte.
On non-supporting platforms, the abstract address is interpreted as an empty string and fails gracefully, generating a runtime error.
This option shares the same semantics as CURLOPT_UNIX_SOCKET_PATH(3) in which documentation more details can be found. Internally, these two options share the same storage and therefore only one of them can be set per handle.
Default is NULL.
curl_easy_setopt(curl_handle, CURLOPT_ABSTRACT_UNIX_SOCKET, "/tmp/foo.sock"); curl_easy_setopt(curl_handle, CURLOPT_URL, "http://localhost/");
Added in 7.53.0.
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
